Slow upload speeds (again)

Hi, a couple years ago I was experiencing slow upload speeds. I made this post and eventually everything ended up okay: https://forums.cox.com/forum_home/internet_forum/f/internet-forum/18313/very-slow-upload-speeds-download-speeds-are-fine

By okay, I mean that I was mostly getting a 10 Mbps upload (which is exactly what my plan supports). That lasted up until recently, and I'm experiencing similar problems again. My download speeds are fine, but my upload speeds never seem to hit 10 Mbps anymore and instead hang around 2 to 7 Mbps. The lack of consistency is quite troubling to me and that's why I think this is an issue.

I looked at my modem and saw that over the past month and a half, there's a lot of critical errors, such as T3 timeouts. If you guys want me to produce a log, I can. It has also been incredibly cold here recently, which I know can have an effect on internet speeds, but I feel like it wouldn't matter here since my download speeds are perfectly fine.

Here is a screenshot of my upstream/downstream channels. This is after a reboot initiated from the Cox website about 30 minutes ago: https://imgur.com/a/yjmLq9Z

Can I get some assistance on this? From your point of view, I'd like to know if anything looks wrong. My modem and router have stayed the same over this period of time.

Thanks!

    Hello, we are extremely sorry you're experiencing ongoing issues with the upload speeds, and we'd be glad to assist. At the moment, we're not seeing anything out of the ordinary, and your signal levels look quite healthy. Additionally, we aren't detecting any packet loss. When you experience poor upload speeds, are you on a wired or wireless connection? -Kevin

    The problem has been pretty bad tonight with upload speeds hanging around from 2 to 4 Mbps. I also do see another T3 timeout in my modem's error log.

    Also I noticed in my pictures that the frequency of the downstream channels I'm using has shifted since my post 2 years ago (see this picture and compare it to the one in the initial post: https://imgur.com/a/1MSZY). What would cause this change?

      Hi GoShox1, we may have to send out a service technician for this, especially if you're experiencing slow upload speeds on a wired connection. If you'd like us to send out a service technician, please send an email with this link to our team at cox.help@cox.com. Aside from the few timeouts we see on the modem, everything looks extremely solid. -Kevin M. Cox Support Forum Moderator
